摘要： 城市车辆速度受多种因素影响呈现某种分布，鲁棒的干道协调控制模型应考虑不同速度下的车辆带宽需求。针对速度波动变化干道传统协调控制方法适用性差的问题，分析了带干扰的干道车辆速度时空分布特征，以推荐速度带宽最大与期望带宽最大为目标，提出了考虑车流速度分布扰动的干道绿波最大带宽协调控制方法。针对佛山市同济路4交叉口干道，速度分布扰动干道协调方法能够提供更符合车辆分布特性的协调方案，比Maxband模型和改进的Maxband模型提升约70%和14%的期望带宽。研究结果表明：笔者方法能够降低Maxband模型平均停车次数25%，平均延误45%和平均排队长度17%；针对不同速度期望和方差情况下的灵敏度分析实验表明，该方法能够为干道提供更具有鲁棒性的干道协调控制方案。

Abstract: The speed of urban vehicles is influenced by various factors and exhibits a certain distribution, and a robust arterial coordinated control model should consider vehicle bandwidth requirements at different speeds. To address the problem of poor applicability of traditional coordinated control methods for speed fluctuations on arterial, the spatiotemporal distribution characteristics of vehicle speed on arterial with interference were analyzed. A coordinated control method for the maximum bandwidth of green waves on arterial considering the disturbance of traffic flow velocity distribution was proposed, with the goal of maximizing the recommended speed bandwidth and the expected bandwidth. For an arterial with 4 intersections along Tongji Road in Foshan City, the speed distribution disturbance arterial coordination method can provide a coordination scheme that was more in line with the characteristics of vehicle distribution, which increased the expected bandwidth by about 70% and 14% compared to Maxband and the improved Maxband model. The research results show that the proposed model can reduce the average number of stops by 25%, the average delay by 45%, and the average queue length by 17%. Sensitivity analysis experiments under different speed expectations and variances show that the proposed method can provide a more robust coordinated control scheme for arterial roads.
